Specifications

DescriptionOxidized Bitumen grades are produced by passing air through soft bitumen under controlled temperature conditions. This process gives the bitumen more rubbery properties than penetration or hard grade bitumen, and enables the product to serve a variety of uses in industrial applications.

Applications and usageThe product is suitable for sealing saw cuts and joints where there is expected to be the minimum amount of moving in the joint. The wide temperature range prevents bleeding in high temperature applications. It can also be used for industrial applications such as pipe coating, roofing, waterproofing, flooring, mastics, sound damping, carpet backing, adhesive and electrical applications.

Blown Grade Bitumen shall be broken up into small pieces (for blown grade in molded cake form) and heated slowly to the application temperature of 180ºC to 230ºC.
